Pron users are funny, since the vids they watch have gotten millions of hits they assume most men must also use it. I'd say more men aren't using pron these days, but who knows could be 50/50. I avoid pron completely and have done so for over 5 yrs now. I find the use of it doesn't wreck you mentally at first, but slowly over time. Good luck to you if you're not able to abstain, but for me personally, life, workouts, my relationship with myself and wife are much healthier without it.
There's one supplement I use to take that does help with sperm production called ZMA. Otherwise at 42 I feel great as long as I eat well and workout at least 20 mins - 1 hour a day and of course get plenty of sleep and sex. Never tried TRT but if it gives you the drive I had in my 20's I'm steering clear….
